Intended Use
The WE and OW Friction Wrists permit the terminal device to be rotated to any position and come with a removable, replaceable friction insert. The WE Infant Friction Wrist is designed for pediatric patients and has a pressed-in, non- removable insert.
Product Features
- Permits terminal device to be rotated to any position
- Friction is easily adjusted by a set screw in the body of the wrist
- The friction insert has stainless steel lead threads and is replaceable (except the WE-100N Infant)
- Oval design option for long transracial and passive hands
Storage and Handling
It is recommended that prosthetic wrists be stored in a cool, clean, dry
environment away from harsh chemicals (chlorine, acids, acetone, etc.).
Performance Characteristics
Material: Aluminum, Stainless Steel, Nylon
The device is intended for single user/patient use only.
Warnings and Precautions
NOTICE: An upper-limb prosthetic device user’s ability to drive should be
determined on a case-by-case basis by a specialist. Contact your local
governing authorities regarding any driving restrictions or limitations.
WARNING: Body-powered devices should not rely on cable tension for grasp
control if the user has been cleared to drive with the prosthesis.
Failure to maintain tension while controlling the steering wheel could cause
serious injury or death.
CAUTION: Do not tighten the friction screw without first inserting a
terminal device with a ½-20 thread.
CAUTION: Abnormal or improper environmental conditions will lead
to malfunctioning and damage of the prosthesis and are not covered under the
warranty of the device. This prosthetic component must not be subjected to
dust/debris, liquids other than fresh water, abrasives, vibration, activities
which would damage the biological limb, or prolonged extreme temperatures (<
-5 °C or > 50 °C). Do not allow debris or liquids
to remain in the prosthesis and its components during use. Rinse the wrist
with fresh water and dry immediately after exposure.
CAUTION: The wrist unit is waterproof to 1 meter. However, if the wrist
is submerged, it should be rinsed with fresh water and dried immediately to
remove salt, chlorine, or debris.
Qualified Provider
Attachment, adjustment, alignment, and delivery of this device must be
performed by or under the direct supervision of a qualified prosthetist.
Unless stated in this manual, any such activities should not be attempted by
the user and will potentially void the device warranty.
Specifications and Preparations Before Use
(Risk Management for Installation and Calibration)
Alignment
Prosthetic wrists should be aligned to provide the best possible work envelope
for the patient’s specific goals. Standard alignment begins at 5° of flexion
and 5° of radial deviation but should be tailored to the individual patient.
Lamination Instructions
-
Place the wrist unit on the distal end of the forearm mold (beeswax, foam, plaster, or similar). Be sure that the internal components do not contact the inner socket.
-
The wrist may be laminated by removing the friction components from the wrist body.
-
A PVA bag should be used to separate the wrist from the forearm mold if foam or plaster are used.
-
Wax the interior surface of the wrist and the distal face of the wrist body.
-
Pack the wrist with silicone fitting gel or similar to prevent it from filling with laminate.
-
Mask the housing distal to the tie-in groove on the body to preserve access to any moving components and to keep all laminate clear of the distal end.
-
Laminate with the appropriate materials for durability and finish as desired
by the patient, being sure to tie each structural layer into the tie-in groove in the body. -
Carbon fiber tape is a good choice for reinforcing the connection to the body and is commonly used for distal to proximal strips tied in with circumferential wraps.
-
When reattaching the internal components, use medium-strength thread locker on the attachment screws before delivery.
